Convert to WebP, without the upload step

WebP is a modern image format that supports lossy and lossless compression as well as transparency. Converting a photograph to WebP can reduce its download size while keeping useful visual detail. It is supported by current major browsers, content management systems, and many image workflows.

Select your images, choose an output format and quality, then process them in parallel browser workers. Nothing is sent to a conversion service. Each finished result includes a preview and file size, and a batch can be saved as one ZIP archive.

When transparency is important, choose PNG or WebP rather than JPEG. JPEG does not support transparent pixels. The browser decodes source orientation before encoding, which helps keep phone photos upright. If a format cannot be decoded by your browser, the tool reports that file as an error while continuing with the rest of the batch.

Private image processing

Files are decoded and processed on your device. They are not uploaded to an ImageKit server, and the original files are never overwritten.

Frequently asked questions

Will WebP work on my website?

WebP is supported by current versions of major browsers. Check your publishing platform if you need to support legacy software.

Can WebP keep transparency?

Yes. This converter preserves transparent pixels when the source image has an alpha channel.

Are files transferred to a server?

Your image stays in this browser tab. Processing runs locally on your device; the image file is not sent to an ImageKit server.
